Application filed October 24, 1904:. Serial No. 229,758.

To (all whom it may concern:

Be it known that I, FRED NEELANDS STUBBs, shingle manufacturer, asubject of the King of Great Britain. and a resident of lonia, county ofIonia, State of Michigan, have invented cer tain new and usefulImprovements in VVeather- Strips,of which the following is aspecification.

My invention relates to improvements in weather-strips; and the objectof my invention is to more particularly design a weatherstrip to beattached to doors and operated by the opening and closing of same inorder to be raised up from the floor or moved down thereonto.

The invention consists, essentially, of a back plate designed to besecured to the door and a front plate sliding against said back plate,

a strip of suitable material suitably secured to said front plate, aspring-controlled rod hori- Zontally held in suitable bearings in saidback plate and suitably connected to said front plate, and other detailsof construction, as hereinafter more particularly explained.

Figure 1 is a general perspective view of my weather-strip, showing sameattached to the bottom of a door. Fig. 2 is an enlarged crosssection onthe line at, Fig. 1. Fig. 3 is an enlarged cross-section similar to Fig.2, showing the front plate moved downward. Fig. 4 is a transversesectional view through the door and part of frame, showing a plan viewof part of my weather-strip and also the means used for operating same.

In the drawings like characters of reference indicate correspondingparts in each figure.

A is the door, and B the back plate suitably secured thereto. The backplate B is preferably bent, as shown at b, so that a strip O of suitablematerial, such as rubber or oil-cloth, may be secured thereto.

1) is the front plate. This front plate has sliding movement against thefront side of the back plate B. As will be seen from the drawings, theends E of the back plate are bent over, so as to form guideways for theends of the front plate. The front plate D is bent, as shown at d, sothat the free end of the material C may be attached to said plate. Thesaid plate D is further bent, as shown at 6, so that a strip F of rubberor other suitable material may be secured to said plate.

Having longitudinal movement in the guides a, secured to or forming partof the back plate B, is a rod Gr, on which is a spring H, one end ofwhich is secured to said rod and the other end to the back plate B, asshown at h. The spring H is always exerting a force on the rod G in thedirection shown by arrow in Fig. 1. In its normal position thefrontplate D is up in the position shown in Figs. 1 and 2, thus keeping thestrip of rubber F clear of the floor. The door shown in Fig. 1 isslightly ajar. It will be seen from Fig. 1 that the end of the rod Grprojects beyond the side of the door and is provided with a small rolleror wheel I. When the door is closed, the wheel or roller I abuts againstthe contact-piece J, suitably secured to the frame K of the door, thusforcing the rod G in the direction indicated by arrow in Fig. 4:, thusmoving the front plate D and its strip of rubber F down into theposition shown in Fig. 3. In this position it will be understood thatthe strip of rubber F or a strip of any other suitable material will beforced right down upon the floor, and thus prevent any draft fromgetting thereunder.

3 represents bell-crank levers pivoted to the back plate B, and by meansof the link 4, pivoted to the front plate D, are connected to said frontplate. When the rod G is forced in the direction indicated by arrow inFig. 4, (by the closing of the door.) it moves the links 2, pivotedthereto, (which links are also attached to said bell-crank levers,) soas to operate said bell-crank levers and force the plate D downward. soas to move the strip F tight upon the floor. It will of course beunderstood that immediately the door is opened the spring H returns therod G and its connected parts into the position shown in Figs. 1 and 2.From my invention it will be understood that the strip F has no rubbingcontact with the carpet or floor, and consequently is not Worn out.

It will of course be understood that the bellcrank levers 3 are pivotedto the front'plate D in such position that the said plate will haveequal movement throughout its length and is absolutely prevented frombending against the back plate B. I preferably make use of the strip Gin order to prevent any draft from entering the room between the platesD and B, but do not confine myself to using same.

It will of course be understood that my weather-strip can be attached todoors or windows that have vertical movement.

I do not confine myself to the exact concan be altered in various wayswithout departing from the spirit of my invention.

-What I claim as my invention is 1. A weather-strip comprisinga backplate; a front plate operating thereagainst; a strip of suitablematerial secured to said front plate.

and said back plate and arranged so as to span the opening therebetween;astrip of suitable material secured to said front plate and designed tobe moved down upon the floor; a

rod held parallel to said plates; a spring controlling movement of saidrod so as to keep said front plate and its strip at normal position outof contact with the floor; links pivoted to said rod; bell-crank leverspivoted to said back plate and to said links, and links pivoted to saidbell-crank lever and to said front plate, one end of said rod projectingbeyond said plates.

2. A weather-strip comprising a back plate; a front plate operatingthereagainst; a strip of suitable material secured to said front plateand said back plate and arranged so as to span the opening therebetween;a strip of suitable material secured to said front plate designed to bemoved down upon the floor: a rod held parallel to said plates; a springcontrolling movement of said rod so as to keep said front plate and itsstrip at normal position out of contact with the floor; links pivoted tosaid rod; bell-crank levers pivoted to said back plate and to saidlinks; links pivoted to said bell-crank lever and to said front plate,one end of said rod projecting beyond said plates, and a'roller pivotedin said end.

3. A weather-strip comprising a back plate the ends of which are bent orlapped round so as to form guideways for the front plate; a front plateoperating ,in said guideways; a strip of suitable material secured tosaid back plate and said front plate and arranged so as to span theopening therebetween; a strip of suitable material secured to said frontplate and designed to be moved down uponthe floor; a rod held parallelto said plates; a spring controlling movement of said rod so as to keepsaid front plate and its strip at normal posiplates, and a rollerpivoted in said end.

4:. In combination with a door, and a contactpiece, of a weather-stripcomprising a back plate the ends of which are bent or lapped round so asto form guideways for the front plate; a front plate operating insaidguideways; a strip of suitable material se-- cured to said backplate and said front plate and arranged so as to span the openingtherebetween; a strip of suitable material secured 1 to said front plateand designed to be moved down upon the floor; a rod held parallel tosaid plates; a spring controlling movement of said rod so as to keepsaid front plate and its strip at normal position out of contact withthe floor; links pivoted to said rod; bell-crank levers pivoted to saidback plate and to said links; links pivoted to said bell-crank lever andto said front plate, one end of said rod projecting beyond said plates,and a roller pivoted in said end, the said roller, when the door isclosed, designed to abut said contactpiece so as to operate said rod anddepress said front plate.

5. A weather-strip comprising a back plate; a front plate operatingthereagainst; a strip of suitable material secured to said back plateand to said front plate and arranged so as to span the openingtherebetween; a rod held parallel to said plates; a spring controllingmovement of said rod so as to keep said front plate'at normal positionout of contact with the floor, and means connecting said rod to saidfront plate so that said front plate will be moved when said rod ismoved.

In testimony whereofl have signed my name to this specification in thepresence of two subscribing witnesses.
